I have Proxmox on my node server which have ip:5.189.190.* and I created openvz container on an ip : 213.136.87.* and installed centos 6 on it

Hello
As the title says, novnc is not working for me.
I get:
"noVNC ready: native WebSockets, canvas rendering" then after a view seconds: "Server disconnected (code 1006)"
I tried with latest chrome stable and Firefox under Linux and Windows.
Any suggestions what could be wrong? Do i need to open additional ports in the firewall? Port 8006,5900,3128 are open, vnc and spice works fine.

I have recently ordered a vps from a provider. Normally I get an email with my credentials and a link to manage my vps, but this time i got an email with just an ip and my root credentials. i asked them if I do not get a control panel to manage my VPS and they said Proxmox does not has such a future for clients.
Now I need to reinstall my VPS, but the support is very slow. I am already waiting for 36 hours now and still no reinstall from their side.
Is it true we do not get a client panel to control the vps?

What is the limiting factor(s) when performing storage migration on a running VM?
When performing storage migration (NFS => NFS backends), we see a 750Mbit/s average transfer speed when doing storage migration on a VM that is switched off. On a running VM we see 300Mbit/s average on the same configuration. The best I have ever been able to achieve on a live storage migration is 450Mbit/s but I can't repeat that, and it wasn't sustained anyway. I have tried this on PVE v3.0, 3.1, and now 3.3 with very little variation in the results. There is negligible other storage network activity for the whole time of the migration (~20Mbit/s), so it's not interference from another network device.
Since I have verified that this is not a hardware limitation, I would like to know what it is about a running VM that is the bottleneck so I can tune the speed of live storage migration.

Hi there,
fence_node using fence_ipmilan is not working, alway returns status failed.
This is the latest pve-version, there was something mentioned in the changelog, but nothing to specific
pveversion

ipmitool is working
ipmitool -I lanplus -H '172.24.10.91' -U 'papagena' -P ' ' -v chassis power status Chassis

fence_ipmilan is working as expected, using a script for the password
fence_ipmilan -a 172.24.10.92 -l papagena -S /usr/local/bin/FOSubnetPW.php --action=status
Status: ON
Although the password script is written in php, it is in fact a CLI, it could have been named "FOSubnetPW.sh" as well
fence_node -S paymox-02 -vv

status paymox-02 failed -1
or if we try to reboot the node:
fence_node paymox-02 -vv
fence paymox-02 dev 0.0 agent fence_ipmilan result: error from agent agent args: nodename=paymox-02 agent=fence_ipmilan lanplus=1 ipaddr=172.24.10.92

Actually, I tried without my fancy password scirpt, did not work either. Any ideas, howto get fencing up and running?

Hello,
I'm attempting to set up Comstar to use for kvm's .
omnios + napp-it are already working.
I've 4 1-TB disks set to raidz .
I'm looking for help on the correct way to set up Comstar to use with PVE.
My guess is to do the following from Comstar menu in napp-it :
1- create a volume .
Is just one large volume needed or one per kvm?
should ' thin provision ' be set ?
2- do logical units and targets need to be created?

Hello,
I am trying to install Ubuntu 14.04 to a VM, but booting from it doesn't work. The installation works well and without errors.
Once I started the VM, I get the following error from GRUB.
Quote:
error: invalid arch-independent ELF magic.
I am using latest version of Proxmox, Debian and I have Kernel version 3.10.
Any ideas?

Running Proxmox 3.3, my Virtual Machines cannot access the web interface, with a page not found error in Internet Explorer. They can ping the host just no web interface. The web interface is accessible from machines on the network away from Proxmox. Firewall is not enabled on any of the machines.
Any ideas? I'm trying to access via IP address, so don't think this is a DNS issue. The VMs can access other resources on the local network via the browser, just seemingly not PVE.
Thanks,
James

Hi
I have been trying to install Proxmox 3.1 and 3.3 on what I class as a "Micro Pc"
First with a Mac Mini (not out of choice) - which didn't end well
Second with a GigaByte Brix i7H-4500U - Which is currently being return after I nearly chuck it across the room.
I am considering a an Intel NUC now but I don't like the spec for them.
I wanted to see if anyone has had any success with using a Micro PC and if so what model and specs?
Thanks!

Hi,
I have currently three node cluster, one node on 3.3 and two on 3.2.
It was running without any problem but today I had to restart one nfs server.
I received some error logs about vanished connections and servers stopped to "see" each other on the web page.
I experienced this few months ago but it was solved by turning on nfs server again and restarting pvedaemon, pveproxy and pvestatd.
Not this time. I get no messages in syslog or anywhere else.
All shared storage are available on all nodes but other nodes are marked red on each other web frontend.
Directory /etc/pve is mounted and pvecm nodes or status shows correct values. Problem is just with the UI.
Thanks a lot for your help

Hi,
I have a running 1.7 proxmox server with 2 VM and I wish to migrate to a new 3.x proxmox server.
The first VM runs a Centos + Parallel Plesk so I have no problem to migrate it using the plesk import sites functionality, the second one runs UBUNTU with a radius server. I am planning to migrate it using the proxmox backup-restore.
The question is: could I restore on a 3.x proxmox server a VZdump backup done by a 1.7 proxmox server?
I cannot stop the service for more than 10-15 minutes
everyone have any tips?
thx

Hi to all Proxmox fans!
I want to migrate my iptables-persistent firewall to the new Proxmox firewall and I have several
problems.
I have 5 public IPs on the host with one NIC.
All with /32 network.
The Public_IP_1 is Proxmox host itself.
I have 5 VMs. One is nated behind Public_IP_1.
Nated_IP is 10.10.10.1.
Here are the nated rules:
*nat
:PREROUTING ACCEPT [1243:60803]
:POSTROUTING ACCEPT [705:46567]
:OUTPUT ACCEPT [668:44567]
-A PREROUTING -d Public_IP_1 -p tcp -m tcp --dport 2121 -j DNAT --to-destination 10.10.10.1:22
-A PREROUTING -d Public_IP_1 -p tcp -m tcp --dport 80 -j DNAT --to-destination 10.10.10.1:80
-A PREROUTING -d Public_IP_1 -p tcp -m tcp --dport 443 -j DNAT --to-destination 10.10.10.1:443
-A PREROUTING -d Public_IP_1 -p tcp -m tcp --dport 8000 -j DNAT --to-destination 10.10.10.1:443
-A POSTROUTING -s 10.10.10.0/24 -o vmbr0 -j SNAT --to-source Public_IP_1
COMMIT
I can not see how to manage that with the Proxmox firewall.
Second problem is related to bridge firewalling.
To use iptables for that I enabled net.bridge.bridge-nf-call-iptables = 1.
For that I need the FORWARD table.
Here is an example:
*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT DROP [0:0]
:LOGGING - [0:0]
-A FORWARD -p tcp -m physdev --physdev-in tap+ ! --syn -m state --state NEW -j DROP
-A FORWARD -p tcp -m physdev --physdev-in tap+ -m state --state NEW,ESTABLISHED -j ACCEPT
-A FORWARD -p udp -m physdev --physdev-in tap+ -m state --state NEW,ESTABLISHED -j ACCEPT
-A FORWARD -p icmp -m physdev --physdev-in tap+ -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
-A FORWARD -p tcp -m physdev --physdev-in eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
-A FORWARD -p udp -m physdev --physdev-in eth0 -m state --state ESTABLISHED -j ACCEPT
-A FORWARD -p icmp -m physdev --physdev-in eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
-A FORWARD -p icmp --icmp-type 0 -j ACCEPT
-A FORWARD -p icmp --icmp-type 8 -j ACCEPT
-A FORWARD -p tcp -d Public_IP_2 --dport 80 -j ACCEPT
-A FORWARD -p tcp -d Public_IP_2 --dport 443 -j ACCEPT
and so on.
In the Proxmox Firewall there is no FORWARD table.
Is this possible somehow?
Best regards

Given that Proxmox performs live/storage migration over SSH I think this would be pretty significant
http://www.psc.edu/index.php/hpn-ssh
Any chance of a deb file for a compile using this patch? Our cluster is linked over 10gbe so getting 50-100 MBytes/sec for something like live migration was previously confusing.
Thanks!

Hi,
i've setup my proxmox to backup to a nfs target every night. I receive mails when the backup is finished, that's great.
Yesterday a switch failed and the proxmox system could not access the nfs anymore. I would assume to get a email from proxmox that it was not possible to perform the backup. But instead nothing happened.
The logs do not even hint at the failure. There is a log entry in proxmox for 22.09.2014 4:00 with the last successful backup and then nothing more.
What I would love to see:
* get a email that it was not possible to perform the backup
* get a log entry that it was not possible to perform the backup
Regards
